如何在ios应用扩展中上传

Question

如何在ios应用扩展中使用AFNetworking上传？

苹果的例子使用了NSURLSession，你能给我解释一下它是如何工作的吗？

- (void)didSelectPost {
NSExtensionItem *imageItem = [self.extensionContext.inputItems lastObject];


// Verify that we have a valid NSExtensionItem
if (!imageItem) {
    return;
}

// Verify that we have a valid NSItemProvider
NSItemProvider *imageItemProvider = [[imageItem attachments] firstObject];
if (!imageItemProvider) {
    return;
}

// Look for an image inside the NSItemProvider
if ([imageItemProvider hasItemConformingToTypeIdentifier:(NSString *)kUTTypeImage]) {
    [imageItemProvider loadItemForTypeIdentifier:(NSString *)kUTTypeImage options:nil completionHandler:^(id item, NSError *error) {
        if (item)
        {

            NSData *data = [NSData dataWithContentsOfURL:item];
            [self method:data];
        }

        [self.extensionContext completeRequestReturningItems:nil completionHandler:nil];
    }];
}

}

如何使用此方法或使用AFNetworking或使用我的应用程序上传此数据？

- (void)method:(NSData *)data
{
    NSString *confName = @"com.example.photoblog.backgroundconfiguration";
    NSURLSessionConfiguration *conf = [NSURLSessionConfiguration backgroundSessionConfiguration:confName];

    NSURLSession *session = [NSURLSession sessionWithConfiguration:conf delegate:self delegateQueue:nil];

    NSURLRequest *requeust = [self requestForExtensionItems];
    NSURLSessionUploadTask *upload = [session uploadTaskWithStreamedRequeust:request];

    [upload resume];

}

你应该设置你的扩展和包含应用的应用组，然后像这样配置会话

config.sharedContainerIdentifier =  @"group.xxxxx";
